For this reason, thefeed groove of the l\-2 triple valve is made the same size as theK-i, so that it is necessary in the I\-2 triple to increase the charg- M\ 0j. ^//>///////////////////Z\ R 31 y//////////////////A Fig. I.

In order todo this, the small port / is added to the slide valve of the K-2triple valve only; this port registers with port y in the slide-valve seat, when in the full release position. Air then passesfrom chamber Y, through ports y and y to chamber R, and theauxiliar} reservoir. Urake-pi])e air in a. raises check valve 15and supplies chamber Y with air as fast as it is required.
